The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.

AbstractMy purpose with this study was to learn more about different ways to teach children how to read and to investigate how teachers can use more fiction when they teach.During the years that I have been working in school, I have only met teachers who use a method that is built on sounds. The children learns to read from books where the words is not put in their right purpose; for example; we can se a sun, a dear looks down in a lake.After my teacher-education in literature I became more and more interested in if it could be possible to use more fiction when you teach children how to read. I also wondered if it was possible to find readers where the sentences are put in a meaningful story.I heard of a method called Whole Language, or the kiwi-method and I decided to find out more about that method. I decided to make a comparison between the ?sound-method? and the Whole Language-method.I have been using qualitative interviews with both children and teachers with experience from these different ways of teaching.

The purpose of this master?s thesis is to describe by a gender approach what ideas and values are expressed in the novel One Night at Bullar Lake and how they do coincide to a tendency. We also want to discuss authority and class divisions and how these can be connected to the novel and the author. Our final question is to examine in what way the voice of the female author is represented in the novel. To approach our material we use Yvonne Hirdman?s theories about the construction of sexes and Susan Sniader Lanser?s work about voices of female authors, as well as Horace Engdahl?s studies about the silent voice in literature.

All my short stories have been written in an intuitive way according to which no outline of characters, intrigue or plot was made in advance. A consequence of this process is that not even myself as the author is aware of the meaning of the texts and therefore I too have to interpret the stories. Because of the character of the text, I use an analysis of archetypes according to C. G. Jung?s analytic psychology.

Kroppens prestation försämras vid höghöjdsvistelse pga. syrebrist och individer kan drabbas av akut höjdsjuka (AMS). Samtidigt acklimatiserar sig kroppen genom att bl.a. öka syreupptaget som kompensation för det låga syretrycket. Studiens syfte var att undersöka hur hemoglobinkoncentrationen (Hb) påverkas av hög höjd och om det finns någon korrelation mellan Hb i vila eller Hb-ökningen under arbete tillika individers välmående på hög höjd.

What is located on the bottom in the water outside of Birka? Remains of a water palisade or jetties and other constructions.Birka a Viking Age town that existed between AD 750 and 975 was located on the northwestern part of the small island of Björkö, in the Mälar archipelago of the Baltic Sea in Sweden. The Town was protected onshore by a hill fort and a town rampart. It is a widely spread assumption that Birka had a water palisade as a part of its defense. There are logs and other remnants on the bottom of the lake dating back to the Viking age.

Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.

Stormwater in urban areas has been treated as a problem for a long time. The large proportion of impermeable surfaces inhibits the water from infiltrating in the ground to the same extent that it does in nature. This causes intensive surface flow during rain, which in turn causes inconveniences such as decreased accessability, floods and increased risk of desease spreading. Drainage through pipes is the traditional and usually functional metod for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation.

That ecological and evolutionary processes can take place on the same time scale is a recent insight. Today we also know that they are directly linked to each other. In the lake Tåkern, in year 2000, there was a structural change when phytoplankton declined and submerged vegetation, mainly stoneworts began to spread. This led to evolutionary changes in the aquatic sowbug, Asellus aquaticus which had previously been limited to the reed, most likely feeding on detritus. But then, sowbugs could exploit the new habitat in stoneworts and a new food resource in terms of periphyton.

Due to the forest industry downsizing, many communities in rural forest regions in Canada and Sweden are facing problems to survive. In order to create community sustainability, resilience and well-being in remote forest regions, the view on the forest resources has shifted towards multiple use, through the concept of sustainable forest management (SFM). Beside the economic and ecological elements of sustainability, the social forest values are needed, contributing to the human well-being, local participation, stakeholder collaboration, human rights and cultural connection. In this thesis the embodiment of the social component of SFM within Prince Albert Model Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners and facing similar challenges as rural boreal forest regions, the two model forests are compared through analysis of projects and activities, conducted interviews and organization documents. Looking at projects mentioned as successful by the interviewees, they all have elements from the social values of SFM. The direction can be explained by the introduction of the Forest Communities Program in Canada, demanding the Model Forests to work towards community stability and resilience, the Model Forest organization concept itself and the way global focus are increasing around social forest values. In the future, it may be important that the role of the MFs enable some kind of political authorization and legitimacy in order to improve conflict solving and indigenous rights equality.

Epifytiska lavar utgör en viktig del av floran i den boreala zonen. Några miljövariabler är kända för att styra artrikedomen och artsammansättningen av epifytiska lavar på beståndsnivå, såsom träddiversitet, beståndsålder, fuktighet och trädens barkstruktur. Skogsbränder utgör den viktigaste störningen i boreala skogar men studier på brandeffekter på epifytiska lavar är mycket få. Detta arbete undersökte artrikedomen, diversiteten och artsammansättningen av epifytiska lavar på basala delar av björkar längs en gradient av 30 skogsbeklädda öar som skiljer sig i storlek och brandhistorik i den norra boreala zonen i Sverige. Målet med studien var att undersöka hur lavfloran påverkades av östorleken och miljövariablerna längs gradienten.

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

This essay is a study and analysis of the funnel beaker pottery at Gullarve 1:13 in Väte parish. The purpose of the study is to analyse the chronology of the settlement by determine the distribution, stratigraphic context and the ornamentation of the pottery. Another purpose is to discuss the geographical location of the settlement in the landscape.In this essay a short review of the pottery and the funnel beaker culture as well as a description of the pottery from the archaeological excavation from 1984 at Gullarve 1:13 is presented. Since the documentation of the archaeological excavation from 1984 is missing or is very inadequate, no spatial analysis can be carried out. The distribution of the pottery can?t contribute to the result of the essay, though if possible it probably would have provided some interesting results.

The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.

The Savi?s Warbler (Locustella luscinioides) is a recently established bird species in a few reedy shallow lakes of southern Sweden and has only been found nesting for the last twenty years. Little is known about the species' habitat preferences, breeding biology and demands for specific territory structures at breeding sites in Sweden. Knowledge of a newly established species? habitat requirements is essential to maintain a viable population and design action plans.
